vector digital data
The Streams file is intended to serve as the location of flooding source where the ABFEs were analyzed and further used in the Hydraulic analysis.
Intended to use to show the flooding source name along with spatial location. A stream network was developed by leveraging FEMA’s CNMS centerlines and NHD high- to medium-resolution data for unmapped areas.

This product is not be used as information to support regulatory floodplain designation or insurance ratings. Use of data is to provide the FEMA with guidance to disseminate to communities rebuilding after Hurricane Maria. The advisory elevations do not include freeboard and/or any additional safety factor to account for potential future increases of the coastal flood hazard due to sea level rise. Advisory mapping information was not adjusted to provide a seamless tie to any existing hazard Flood Insurance Study (FIS) mapping in adjacent areas.

This layer includes a field that stores unique identifiers for each feature in the feature class. This identifier is an 8-digit number, where the first three digits are the same as the last three digits of the HUC10-watershed number, and where the last five digits are the hydrologic model ID number for its corresponding stream feature. Thus, the hydrologic model can be found in the STREAM_ID field. For hydrologic models that included a lettered suffix, or where the stream feature had to be split for other reasons, the STREAM_ID had to be modified. These modifications are: Río de Aibonito (Tramo Lateral); Model ID 14492a became STREAM_ID 50794492. Río de la Plata (Tramo Abajo); Model ID 14093a became STREAM_ID 50794093. Río de la Plata (Tramo Arriba); Model ID 14093c became STREAM_ID 50784093. Río Santiago (Tramo Lateral); Model ID 11954a became STREAM_ID 50291954. Model ID 14536 for the portion on Río Usabón (Tramo Abajo) became 50794536. Model ID 14536 for the portion on Río de Barranquitas remained 50714536. Spanish language terms used in the database, with their English translations or equivalents are: Afluente = Tributary; Modelo núm. = Model No.; Núm. (for número) = No. (for number); Río sin nombre = Unnamed stream; Tramo Abajo = Lower Reach; Tramo Arriba = Upper Reach; Tramo Lateral = Lateral Reach or Side Branch.

Hydrologic and hydraulic modeling were conducted at the HUC10-watershed level. Data within each HUC10-level analysis were subjected to topological and other checks to ensure spatial accuracy by manually verifying against Terrain data and Aerial imagery. These lines were reviewed and modified to more closely follow the thalweg of the stream.

Data within each HUC10-level analysis were subjected to topological and other checks to ensure spatial accuracy by manually verifying against Terrain data and Aerial imagery. These lines were reviewed and modified to more closely follow the thalweg of the stream.
The streams that were used in the Hydrologic and hydraulic modeling efforts were checked against the original scope. Any discrepancy in stream length is verified and attributed various factors such as stream segments partially or completely influenced by coastal analysis etc
A visual inspection of attribute tables was conducted to ensure that all necessary attribute fields were populated according to the received guidance. A GIS-based review was performed to ensure that the correct geographic attributes applied to the proper features, and that features were correctly located relative to each other. Data were not subjected to any statistical checks for accuracy.
Feature delineation was based on topographic/aerial datasets in conjunction with analyst interpretation of those data. The delineation is subject to the accuracy constraints of those data, and as with any engineering analysis of this type, variation is possible.
